Abstract
The utility model relates to a spiral anti-theft lock, which comprises a lock core, helix top wire, a head of the lock, a transom and a U-shaped ring. The utility model is the vehicle lockset adopting excellent quality steel. Comparing with a plurality of prior locksets, the lock is opened through the rotating key 1080 degrees when unlocking. The utility model has the advantages of having good safety and being applied to a plurality of cars.
Description
The utility model provides a kind of screw mechanism that adopts to prevent the spiral theftproof lock that vehicle is stolen.
At present, the lock that is used for various vehicles such as bicycle, motorcycle, tricycle mostly adopts the general expression structure, inserts the key dextrorotation when unblanking and turn 90 degrees, and without key, by spring action lock is lived during the lock car.Existing lock is typical case's representative with the U-shape lock, and this lock inner spring withstands dead bolt, and dead bolt withstands the groove on the U type ring.If U type ring is subjected to external impacts, just be easy to be opened.
The purpose of this utility model is: improve on the basis of existing U-shaped lock, design a kind of spiral anti-money lock that adopts screw mechanism to pin various wheel of vehicle.
The utility model is achieved in that this spiral theftproof lock mainly is made up of key, lock core, drive link, spiral jackscrew, tapered end, U-loop, crossbeam, beam head, snap ring each several part.U-loop, tapered end, beam head adopt the mode of welding in the hole to connect.When unblanking, key is inserted lock core, inhour rotation 1080 degree, lock core drives drive link and rotates in spiral jackscrew groove, and the spiral jackscrew is return, and crossbeam is extracted out, and lock is opened.At the crossbeam front end snap ring is housed, guarantees that crossbeam is unlikely to extract out fully when unblanking.Lock inserts crossbeam in the tapered end hole earlier during car, key 1080 degree that turn clockwise, and lock core drives drive link and rotates in the spiral jackscrew, and the spiral jackscrew is protracted, and heads in the crossbeam groove, with crossbeam lock jail.
Advantage of the present utility model is: simple in structure, interlocking is firm, easy to operate, safe and reliable.
Concrete structure of the present utility model is provided by following drawings and Examples:
Accompanying drawing has provided the overall structure schematic diagram of this spiral theftproof lock, has provided cross-sectional drawing among the figure in the middle of crossbeam and in the middle of U type ring.
In the accompanying drawings, [1] is key, and [2] are lock core, and [3] are drive link, and [4] are the spiral jackscrew, and [5] are tapered end, and [6] are U-loop, and [7] are beam head, and [8] are crossbeam, and [9] are snap ring.
This spiral theftproof lock includes key [1], lock core [2], U type ring [6], crossbeam [8] each several part.Be connected with drive link [3] in the termination of lock core [2], drive link [3] rotates synchronously with lock core [2].Drive link [3] is connected with spiral jackscrew [4] by the groove on the spiral jackscrew [4], and drive link [3] is clockwise or be rotated counterclockwise, and the spiral jackscrew is also clockwise respectively or be rotated counterclockwise.Spiral jackscrew [4] is by in the hole that is threaded in tapered end [5] on its excircle, and when promptly unblanking, spiral jackscrew [4] is driven the inhour rotation and returns backward; Lock is during car, and spiral jackscrew [4] is driven dextrorotation then stretches forward, withstands on that just crossbeam [8] lock is firm in the groove of crossbeam [8] end.In order to prevent that crossbeam [8] from being extracted out fully, be connected with snap ring [9] in a termination of crossbeam [8].
